Abstract
The utility model discloses a low pressure electrical components arcing distance detecting means when carrying out low pressure electrical components switch -on breaking capacity test, will be installed on the examination article frame of device by examination article, and through the adjusting matching of threaded chang'an dress screw rod with fixation nut, convenient nimble ground fixes the flashover distance pick -up plate in required position, the device structure of realization flashover distance detection. The device can realize in certain extent well, and the arcing safe distance when utilizing arcing distance detecting means to take load combined floodgate / separating brake to low pressure electrical components detects, confirms margin of safety and reliability.
Description
Art
The utility model belongs to electrical apparatus test technology, especially a kind of low voltage component is related to when short-circuit test, in advance according to the arcing safe distance technical parameter of test specimen, the position of adjustment check-out console, whether standard-required is met according to the Information Authentication that check-out console detects, whether consistent with product technology parameter.
Background technology
Low voltage component be a kind of can according to the signal in the external world and requirement, on-off circuit manually or automatically, to realize switching to circuit or non-electrical object, control, protection, detection, the element of conversion and adjustment or equipment.A kind of closed or disconnection main circuit or Large Copacity circuit switching electrical equipment that is used for.Be characterized in cut-offfing larger current, can frequent operation, divide at on-load, when closing a floodgate, electric arc can be produced between contact, to external diffusion, form arcing and cause alternate and shorted to earth accident, therefore, the arcing safe distance of low voltage component is a very important parameter, is must consider in electrical equipment design.
Summary of the invention
The purpose of this utility model is being carried out in low voltage component connection/breaking capacity test to solve, without the problem of the flashover distance checkout equipment of special sizing.
The utility model devises a kind of low voltage component flashover distance pick-up unit, when carrying out low voltage component connection/breaking capacity test, test specimen is installed on the test product frame of device, coordinated with the adjustment of hold-down nut by threaded Chang'an loading screw, easily and flexibly flashover distance check-out console is fixed on desired position, realizes the apparatus structure that flashover distance detects.
The utility model solves the technical scheme that its technical matters adopts:
A kind of low voltage component arcing safe distance pick-up unit, the utility model feature is, is assembled by the metal bracket of rectangular dielectric framed structure, arcing check-out console, the metal long bolt passing across arcing check-out console and metal bracket, the distance adjusting nut that coordinates with metal long bolt; Wherein, arcing check-out console is a rectangular dielectric frame, is provided with wire netting, offers mounting hole at this rectangular dielectric frame four angles in the middle of this rectangular dielectric frame; On metal bracket, longitudinal arrangement offers kidney-shaped mounting hole, regulates metal long bolt for installing.
The utility model can realize the safe flashover distance technical parameter according to test specimen, adjusts the position of check-out console easily and flexibly, meets testing requirements.
First test needs flashover distance pick-up unit to be positioned on insulcrete, test specimen is fixed in test product rack position, according to the arcing technical parameter of test specimen, turn nut, mobile arcing check-out console, measure the air line distance of wire netting and test specimen arc-extinguish chamber, turn nut fixed test plate when meeting the demands.The wire netting bare copper wire (fuse-link) that meets standard-required directly causes mains neutral point.
During test, three-phase supply enters low voltage component turnover line end, the load of standard-required is brought to start to carry out/separating brake action of closing a floodgate, produce electric arc to external diffusion instantaneously, when electric arc fly out arrive arcing check-out console wire netting when distance exceeds detecting distance time, the arc short-circuit electric current of generation will cause bare copper wire (fuse-link) to fuse.
The beneficial effects of the utility model are, can realize within the specific limits well, utilize flashover distance pick-up unit to carry out detecting to arcing safe distance during low voltage component on-load combined floodgate/separating brake, determine margin of safety and reliability.

Embodiment
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of low voltage component arcing safe distance pick-up unit, the utility model feature is, is assembled by the metal bracket 1 of rectangular dielectric framed structure, arcing check-out console 2, the metal long bolt 3 passing across arcing check-out console 2 and metal bracket 1, the distance adjusting nut 4 that coordinates with metal long bolt 3; Wherein, arcing check-out console 2 is a rectangular dielectric frame, is provided with wire netting 5, offers mounting hole 2.1 at this rectangular dielectric frame four angles in the middle of this rectangular dielectric frame; On metal bracket 1, longitudinal arrangement offers kidney-shaped mounting hole 1.1, regulates metal long bolt 3 for installing.
The utility model can realize the safe flashover distance technical parameter according to test specimen 6, adjusts the position of check-out console easily and flexibly, meets testing requirements.
First test needs flashover distance pick-up unit to be positioned on insulcrete, test specimen 6 is fixed in test product rack position, according to the arcing technical parameter of test specimen 6, turn nut, mobile arcing check-out console, measure the air line distance of wire netting and test specimen arc-extinguish chamber, turn nut fixed test plate when meeting the demands.The wire netting bare copper wire (fuse-link) that meets standard-required directly causes mains neutral point.
During test, three-phase supply enters low voltage component turnover line end, the load of standard-required is brought to start to carry out/separating brake action of closing a floodgate, produce electric arc to external diffusion instantaneously, when electric arc fly out arrive arcing check-out console wire netting when distance exceeds detecting distance time, the arc short-circuit electric current of generation will cause bare copper wire (fuse-link) to fuse.
